Apple Watch rejected but no reason given

Not sure if anyone else has had this issue. I sent my Apple Watch as a trade in for a new series 8 watch. I got an email saying it was rejected but did not give any reason. Two years ago, I sent an iPad and it was rejected but a reason was given but they must have had the wrong item because they said the screen was cracked. It was not and I sold it to another company and got more money than with the Apple trade in. At least I was given a reason for the rejection.

It seems ridiculous not to give a reason. So, basically, they rejected it for no reason. Anyone else have this issue? Any idea why it would be rejected with no reason given?
